"Mannering used a statistical model to calculate accident probabilities
based on his own examination of data from 390,000 accidents recorded by
the Indiana Vehicle Crash Record System. After applying the model, he
concluded that the increased speed limit had no effect on the
probability of suffering an accident nor did it increase the severity of
accidents that did occur.
In 2006, only 5.78 percent of the state's accidents were caused by
unsafe speed, a decrease from 2004. The study also noted that a 15 MPH
increase in the speed limit did not produce a 15 MPH increase in the
actual speed traveled. Instead, real speeds increased only 12 MPH. "
